Producers warned as tick borne disease detected in Nebraska cattle
Farmers and cattle producers are being advised to stay alert after the detection of Theileria, a tick-borne parasite disease, in several regions. The disease affects cattle health and can lead to serious economic losses if not managed properly.
Theileria is mainly spread through the bite of infected ticks, especially the Asian Longhorned Tick, which is known to carry the parasite. Although this specific tick has not been reported in the affected area, cattle brought in from other locations have tested positive. The tick has already spread across multiple regions, increasing the risk of disease transmission.
Apart from tick bites, the disease can also spread through contaminated equipment or other vectors such as lice and biting flies, although these are fewer common sources. Because of this, maintaining clean equipment and proper farm hygiene is essential.
Infected cattle may show symptoms such as anemia, jaundice, weakness, reduced appetite, and difficulty in movement. In severe cases, the disease can lead to death. Early detection is important to prevent further spread within the herd.
Experts recommend strong tick control measures as the most effective way to reduce risk. Good herd management practices, including regular inspection of animals, are also important. Farmers are encouraged to check areas where ticks often hide, such as ears, tail regions, flanks, and under the body.
“The best method of prevention is tick control and good management practices for your herd including external parasite control,” said State Veterinarian Dr. Roger Dudley. “If Theileria is suspected it should be reported to a veterinarian immediately.”
It is important to note that there are currently no approved vaccines or treatments available for Theileria. Therefore, prevention remains the only reliable strategy. Farmers should work closely with veterinarians to choose suitable parasite control methods, especially during warmer months when ticks are more active.
The disease is considered reportable, meaning suspected cases should be immediately brought to the attention of veterinary professionals. This helps authorities monitor and manage outbreaks effectively. In some cases, affected farms may receive support or compensation for losses. \
